There is no charge for taking on board one carry-on bag. Passengers are required to pack lithium batteries in their carry-on, with ends covered (travelers are allowed to have batteries inside devices). Liquids and gels must be in containers of 3.4-oz or smaller; passengers should place all these containers in a zip-top bag no larger than 8"x8" and must be able to close the bag completely.
Domestic passengers should note that carry-on luggage dimensions must be no more than 22" high, 14" wide and 9" deep. However, for international passengers the height + width + length must add up to no more than 45 inches so that there is no limit on the each particular measurement.
The following regulations apply to flights within the United States, the U.S. Virgin Islands, Puerto Rico and Canada: passengers must pay an additional fee per checked bag; fees depend on destination and number of bags. Please visit the American Airlines website for detailed information: http://www.aa.com/i18n/travelInformation/baggage/baggageAllowance.jsp#Excess%20Baggage. The bags' dimensions must add up to 62 inches (height + width + length must be no more than 62 inches). Each bag must weigh up to 50 lbs. Passengers will incur additional charges for going over limit.
Bags checked in under the allowances below must weigh no more than 50 lbs (except for flights going to Brazil) and their dimensions (height + width + length) must add up to no more than 62". Passengers will incur additional fees for bags checked in over the limit.

Passengers traveling to/from/through Asia are allowed to check in two bags.
Passengers to/from/through Europe and India are allowed to check in one bag.
Travelers to/from Brazil are allowed to check in two bags of up to 70 lbs each.
Passengers should tag each of their bags with their name, destination address, phone number and email in case the bags are lost during flight. It is also helpful to include date, flight number and city of departure on the tag. Change this information for each flight to make it easier for luggage handlers to identify your bag should it get lost.
Like many other airlines, American Airlines no longer provides protective plastic bags for checked backpacks. To avoid your pack's straps getting caught during transport, take with you a large garbage bag or other large protective bag and place your pack inside it.
